Ok, thanks that is helpful. I have exported it out without audio from aftereffects and plan to add the audio in after it exports.

One thing I have done is removed the Ray Traced 3D settings on all the comps. The project is 1:30 in length and I have about a 100 compositions where I was using Ray Traced 3D because I created lots of 3D blocks. Anyway, I have managed to get it down from a 700 hour render to a 10 hour render by doing this so it should be alright now.

ya i was going to say get rid of ray trace...For such a useful 3d aspect to after effects they really messed up on this one..even with only 1 layer in ray trace takes forever..do you have element? .also you might want to re think your lighting..intensity of 52,000...its hard to fathom.have you seen the faux 3d expression..i dont know it by heart sorry..
